CHARLES Gr. TILL, OF BROOKLYN, NEW. YORK, ASSIGNOR OF TWO-THIRDS TO OSCAR F. BOOMER AND HENRY R. RANDALL, BOTH OE SAME PLACE.

EVAPORATOR AND DRIER.

SPECIFICATION forming part of Letters Patent No. 244,499, dated July 19, 1881. I

Application filed December 28, 1880. (No model.)

To all whom it may concern:

Be it known that I, CHARLES G. TiLL, of

Brooklyn, in Kings county, and State of N ew' bendsi'or establishing communication between the central pipes detachably secured thereto, so as to afford facility of access, to permit of the cleaning of the central pipes.

They also consist in the combination, with the above, of bends for establishing communication between the external pipes, detachably secured to said pipes and so constructed that when detached they may be moved sufficiently away from the external pipes to afl'ord access to the means for connecting the bends to the central pipes.

They also consist in the combination, with the central and external pipes, of stuffingboxes afl'ording provision for the movement of either pipes relatively to the other pipes through expansion and contraction due to variationsin temperature without causing leakage.

They also consist in the combination, with the central pipes, of pipes for supplying air thereto for drying their contents.

They also consist in the combination, with the external pipes, of pipes for supplying water thereto for cooling the contents of the'central To one of the central pipes is connected in any suitable manner a feed-pipe, 0, leading from a reservoir where the substance to be evaporated, such, for instance, as cider, is contained under hydrostatic or other pressure sufficient to force it through the central pipes.

D designates a pipe leading to the pipe 0 and provided with a cock, under control of which air, hot or cold, but preferably in either case under pressure, may be supplied to dry the contents of the central pipes, A.

E designates a pipe by which steam is conducted from a generator to one of the external pipes B, for heating the contents of the central pipes, and F designates a pipe whereby cold water may be conducted, under control of a cock, to the said external pipe, for cooling the contents of thecentral pipes after the evaporating or drying operation is terminated. A steam-gage, G, connected with one of the external pipes, B, indicates the pressure of steam therein.

H designates a bend, which may be of they same material as the central pipes, and serves to connect them at theirlower ends. Its ends and the adjacent ends of the central pipes are provided, respectively, with left and right hand screw-threads to which are applied couplings K, provided internally with right and left hand screw-threads, serving to connect the said ends of the central pipes. By turning these couplings in one direction the central pipes and bend are connected, and by turning them in the opposite direction the central pipes and bend are disconnected.

7 I designates a bend connecting the external pipes. It may be made of the same material as the said pipes, and its ends and the adjacent ends of these pipes are, respectively, provided on the outer side with left and right hand disconnected therefrom far enough to afford access to the couplings K to manipulate them and disconnect the bend I. Thus provision is afl'orded for removing both bends, to facilitate cleaning the central pipes.

A pipe, L, for carrying 011' water formed by condensation of steam, under control of a cock, may be connected with the external pipes, 13, if desirable.

In lieu of em ployin g a bend, I, the outer pipes may be connected by pipes M, communicating with each other.

Where a large apparatus is required a great number of central pipes, A, and external pipes, B, may be employed, and bends H and I, with their couplings, may be employed to connect them at top and bottom. Thelast central pipe of the series employed may be connected in any suitable manner to an outlet-pipe, N, whence the substance subjected to the apparatus may be carried off.

The substance to be evaporated or dried as it passes through the central pipes is heated by the steam in the external pipes, so that its moisture is drawn off, and it and the moisture escape from the outlet-pipe N.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

l. The combination of central pipes for material to be evaporated or dried, external pipes for steam or other heating agent, and connecting-bends for establishing communication between the central pipes detachably secured thereto, substantially as specified.

2. The combination of central pipes for material to be evaporated or dried, external pipes for steam or other heating agent, and connectingbends for said central pipes, and external pipes detachably secured thereto, the bends for the external pipes being at the middle sufficiently larger than the bends for the central pipes to enable them when detached to be moved far enough away from the external pipes to afford access to the couplings for the central pipes, substantially as specified.

3. The combination, with the central and external pipes, of stufling-boxes permitting of the movement of either pipes relatively to the other without causing leakage, substantially as specified.

4. The combination, with the central pipes, of pipes for conveying air thereto, substantially as specified.

5. The combination, with the external pipes, of pipes for conveying water thereto after the evaporation or drying is completed, substantially as specified.
